How to Construct a JDBC Connection String for MySQL?

JDBC Connection String for MySQL

When establishing a JDBC connection to a MySQL database, you must provide a valid connection string. This string specifies the location and credentials for the database you wish to access.

For the MySQL JDBC driver (Connector/J), the connection string follows this format:

jdbc:mysql://[hostname]/[database_name]

Example:

If your database is hosted on localhost and named test, your connection string would be:

jdbc:mysql://localhost/test

Additional Parameters:

You can also include additional parameters in the connection string to specify the following:

• User: The username to access the database.
• Password: The password for the user.
• Character encoding: The encoding to use for character data.
• Time zone: The time zone to use.

Example with Additional Parameters:

jdbc:mysql://localhost/test?user=username&password=password&characterEncoding=UTF-8&useTimezone=true

Code Example:

To connect to MySQL using these connection strings, you can use the following code:

String url = "jdbc:mysql://localhost/test";
Class.forName("com.mysql.jdbc.Driver").newInstance();
Connection conn = DriverManager.getConnection(url, "username", "password");

By providing the correct connection string and credentials, you can establish a JDBC connection to your MySQL database and access its data.
